BRACELET-CHAIN.

`SPECIFIt'JA'JJION forming part of Letters Patent No. 271,845, dated February 6, 1853.

i 4 Application filed December 4, 1882. (No model.)

To all whom it may concern:

Beitknown that I, HENRY M. HERRING,of North Attleborough, in the county of Bristol and State of Massachusetts, have invented an Improvement in Bracelet-Chains, ot' which the following is a specification.

The nature of my invention consists in an improved fastening for securing the hollow wire links of' a bracelet-chain to each other; and the object of my invention is to construct such chains in a more 'rapid and economical manner thanl heretofore.

Figure 1 is a plan view and partial section of the bracelet-chain. Fig. 2 is a side elevation of y thefastening-wire as bent by machinery previous to forming up the chain. Fig. 3 is asection,taken transversely, of a single tube and fastening-wire.

In the drawings, A A are the hollow wir tubes, arranged parallel to each other in the chain, and B B the bentflattened wires which serve to hold the tubes together. Through the bore of the rst tubeA ofthe chain is passed a straight piece of flattened wire, b, extending beyond the end of the tube, as shown by the dotted lines. The projecting end a of the wire is then bent over the edge of the tube 'until it comes to a position parallel with the unbent portion of the wire within the boreot' the tube, and. leaving a space between the inner side of the bent wire and the exterior surface of the tube sufficient to yreceive a second tube A,

| which is then placed alongside ofthe first tube, over the end a of the wire, and the opposite end, c', of the wire is then bent over and into the end of the second tube, after which anbore of the second tube, passing by the previonslyturned ends of the first wire; and the above-described operation of' bending is conlicicnt length ofchairnis produced. The wire is made speciallyr adapted for the construction of the chain Vby flattening the same prior to insertion into the bore ofthe tube, and a strong and. durable chain is thus made with great ease and rapidity, the ends of the flattened wire being readily bent so far into the bore of forts for separation by pulling upon the chain; and in order to facilitate the operation of putting thischain togetherthe wires may be cut oft' and bent by machinery to the form shown 'in Fig. 2 prior to insertion into the bore ofthe tubes, thus avoiding the lirstabove described bending of one end of the wire by hand.

I claim as my invention- In a bracelet-chain, the combination of the parallel tubes A A and the bent flattened wires B B, substantially as described.
